The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - An information exposure flaw in openstack-tripleo-heat-templates allows an external user to discover the     internal IP or hostname. An attacker could exploit this by checking the www_authenticate_uri parameter     (which is visible to all end users) in configuration files. This would give sensitive information which     may aid in additional system exploitation. This flaw affects openstack-tripleo-heat-templates versions     prior to 11.6.1. (CVE-2021-4180)

Note that Nessus relies on the presence of the package as reported by the vendor.

The remote Redhat Enterprise Linux 8 host has a package installed that is affected by a vulnerability as referenced in the RHSA-2022:0995 advisory.

    Security Fix(es):

    * Data leak of internal URL through keystone_authtoken (CVE-2021-4180)

The remote Redhat Enterprise Linux 8 host has a package installed that is affected by a vulnerability as referenced in the RHSA-2022:8796 advisory.

    Security Fix(es):

    * data leak of internal URL through keystone_authtoken (CVE-2021-4180)

    Other fixes:

    * Before this update, NTP validation did not occur during deployments. Some users reported issues with     cloud authentication failing with invalid tokens due to time not being synchronized between nodes. With     this update, NTP synchronization validation during deployment has been re-enabled. Hosts must be able to     connect to the defined NTP server list. If you previously performed a deployment with invalid or     unreachable NTP servers, after update, the deployment might fail when NTP is validated. Ensure that you     have valid and reachable NTP servers before updating. (BZ#2034095)

    * With this update, director supports specifying overrides for NVSv4 ID mapping when using a CephFS-NFS     back end with the Shared File Systems service (manila). Ceph-NFS with the Shared File Systems service only     allows client access through NFSv4.1+. With NFSv4.1, usernames and group names are sent over the wire and     translated by both the server and the client. Deployers might want to customize their domain settings to     better represent organization users who can access Shared File Systems service shares from multiple     clients. Director supports customizing NFS ID mapping settings through these parameters:
    - ManilaCephFSNFSIdmapOverrides: Allows specifying configuration objects for override with the default     idmapd.conf file used by the NFS service
    - ManilaCephFSNFSIdmapConf: Allows specifying a custom idmapd.conf file for the NFS service (BZ#1917356)

    * Before this update, the ceilometer-agent-compute container could not read the /var/run/libvirt directory     because of an improper volume mount to /var/run/libvirt in the ceilometer-agent-compute container,     resulting in the inability to poll for CPU metrics on Compute nodes. With this update, the appropriate     global permissions have been applied to the /var/run/libvirt directory, and you can poll for CPU telemetry     with the ceilometer-agent-compute container on the Compute nodes. CPU telemetry data is available through     the Compute service (nova). (BZ#2103971)

    * Before this update, the libvirt service started after the ceilometer-agent-compute service and the     ceilometer-agent-compute service did not communicate with libvirt, resulting in missing libvirt metrics.
    With this update, the ceilometer-agent-compute service starts after the libvirt service and can poll     libvirt metrics without Permission denied errors. (BZ#2130078)

    * Before this update, a Telemetry service (ceilometer) user had insufficient privileges to poll objects     from the Object Storage service (swift). The Object Storage service client did not allow the Telemetry     service user to fetch object details. With this update, the Telemetry service user is associated with the     ResellerAdmin role.
    +     Execute the following command to workaround this issue manually:
    +
    ----     $ openstack role add --user ceilometer --project service ResellerAdmin
    ----     +     The associated Telemetry service user can poll Object Storage service object metrics successfully.
    (BZ#2130849)

    * Before this update, systemd stopped the Load-balancing services (octavia) during shutdown, leaving     resources in the PENDING_UPDATE status. With this update, the graceful shutdown duration of the Load-     balancing services is increased, preventing the services from being stopped by systemd. (BZ#2063031)

    * In Red Hat OpenStack Platform (RHOSP) 16.1.9, the collectd processes plugin is removed from the default     list of plugins. Loading the plugin can cause flooding issues and does not provide value when running in a     containerized environment because it only recognizes the collectd and sensubility processes rather than     the expected system processes. Bug fixes and support will be provided through the end of the 16.1.9     lifecycle but no new feature enhancements will be made. (BZ#2101949)
